what point were you trying to prove?
Some people think a country can be made prosperous by more agriculture, or more people working in agriculture. It's quite idiotic. But of course Phknrocket might be trying to prove some other point, I dunno.
Well, there is no doubt that increased ag employment would help rural America. And while the correlation is absolutely clear, a robust ag sector is vital to our economy. We have some of the best farm land on earth and we'd be stupid not to take advantage of that simply because somebody in a third world country could produce less vigorous, less nutritionally balanced foods more cheaply.
America already has the most farmlands in the world. And also the most productive, though that might have more to do with vastly better irrigation and better infrastructure to get the food to market. And we get it done with much less manual labor than developing countries. Don't you think that is better, since it's being produced at a cheaper cost? You could argue we need more farming in America, but it shouldn't and won't be a major source of employment. It should remain right around 2-3%, where it is currently.
